UITableView Cell selected Color?

No need for custom cells. If you only want to change the selected color of the cell, you can do this:

Objective-C:

UIView *bgColorView = [[UIView alloc] init];
bgColorView.backgroundColor = [UIColor redColor];
[cell setSelectedBackgroundView:bgColorView];

Swift:

let bgColorView = UIView()
bgColorView.backgroundColor = UIColor.red
cell.selectedBackgroundView = bgColorView
